WHEEL-MOUNT FOR SPINNING-MACHINES.

Specification of Letters Patent.

Patented A11 3, 1915.

Application filed July 18, 1914. Serial No. 851,687.

Textile machines of the class referred to are usually provided with a plurality of spindles disposed in series, the spindles of each group being rotated by a suitably driven endless belt or band passing around a freely revoluble idle or tension-pulley removably mounted in a support or yoke; the function of the tension-pulley is to automatically take up slackness in the belt, thereby preventing any material variations in the tension or pull of the belt, the result being to cause the spindles of the group to rotate at a practically uniform speed and producing threads or yarn having a correspondingly uniform twist.

The essential object I have in view is to provide the pulley-carrying yoke or support with bearings and a locking device arranged to securely hold in position the ten sion-pulley and its membersagainst movement in longitudinal and lateral directions, while at the same time permitting the pulley and its axle to revolve freely in the bearings.

The device forming the subject of my invention is extremely simple and inexpensive in construction; it is readily accessible and easily actuated; it forms. in connection with the yoke or support and bearings, positive locking means for retaining the pulley, etc., in the normal operative position or relation, in that longitudinal or endwise and lateral movements are prevented, as before stated. The pulley, together with its axle and bearings, may be quickly withdrawn or removed bodily from the supporting yoke by simply retracting the locking or confining bolt permanently connected to the support.

In the accompanying drawings Figure 1 represents, in side elevation, a yoke having a tension-pulley removably mounted therein and provided with my improved locking device normally positioned to prevent the axle bearings from movement in any direction; Fig. 2 is a front view, portions being shown in central section, taken on line 2 2 of Fig. 1; Fig. 3 is a side elevation of the yoke and locking device, the latter being in the unlocked position, with the bearings, axle and tension-pulley omitted; Fig. 4 isa perspective view of the securing-bolt detached from the yoke; and Fig. 5 is a side View of the lower portion of the yoke showing a modi-. fied form of the axle-bearing removably seated and normally confined therein.

A, in the drawings, indicates a take-up or tension-pulley of the type or class referred to, fixed to a center axle a freely revoluble in the bearings 0.

B represents a yoke normally sustaining the said pulley, etc. The yoke member is provided with a pair of laterally spaced apart parallel downwardly extending arms 7),- the free endsof the arms terminate each in a holder portion B having a recessed seat 7) adapted to receive the respective bearings c; the shape of the said seat may conform to the corresponding portion of the bearing. Theupper or head part ofthe yoke has a central extension or neck 7) arranged to connect with and be suspended from a suitable hanger member d. The said yoke arms I) are provided in front with a lug 6 having a vertical perforation?) adapted to receive, guide and support the free end portions of the securing-bolt E, soon to be described. The said bearings c are removably fitted in the said seats of the holder portion B- of the yoke; each bearing being provided witha transverse aperture or score 0 disposed at substantially right angles to the axis of rotaticn of the axle a, and being in alinement with the said perforations b of the respective lugs.

If desired, the bearing members 0 may be provided with non-revoluble anti-friction or self-lubricating bushings f bored to receive the ends of the revoluble axle, substantially as indicated in Fig. 2. The said score may extend wholly or partly around the perimeter of the bearing. If desired, the latter may be polygonal, substantially as shown in ig. 5, in which case the aperture is formed in the front face of the bearing member and in vertical alinement with the perforation b of the lug 6 substantially as before stated.

The forked bolt or looking member E is integrally formed from a length of comparatively stiff material, as steel, the same being bent to produce a central head or tie member 6 which serves also as a handle. The ends of the tie proper are bent parallel in a horizontal plane (see a Figs. 1 and 2) to receive V the said relatively stationary neck 79 ofthe yoke; the material being further bent at rightvangles to produce a' pair of downwardly extending, laterally separated, parallel bolt-arms e 6 having the lower portion e --slidably mounted in the perforations b? of the respective lugs and also arranged to freely enter the aperture or score of the corresponding bearings.

It will bejobservedthat by means of my improvement the pulley-carryingaxle a revolubly mounted in the bearingso, in'turn reino'v-ably supported in the respective recessed seats o'fthe yoke or frame B, is adaptedto positively and accuratelyposition the said par-tsin thefyoke, while atthe same time theen'gagementof the bolt with the adjacent sids'of the apertured or scored port'ion'of the bearings prevents the latter from,move1nent in any direction in said seats] The bolt is'ffitted to slide Without each arm havl ng an open recess or seat formed" iii face ofi its. lower or free" end portion, a bearing removably seated, in each of saidi'ecesses, said bearings adapted tores ceive a revoluble central axle" and being fur.- ther provide'd with an aperture or score, and

a forl're i or bifurcated" endwise movable copies of'thtsapatent may; be obtained for locking bolt, the arms of said bolt being supported and guided inrthe respective arms of said yoke and also arranged to normally engage and interlockwith the said apertured or scored portion of the bearings.

. In vmechanism of the general character described, a forked yoke or frame provided with a pair alining open recesses constituting seats, relatively stationary bearings removably seated in the recesses, each of said bearings having an aperture or score formed in its periphery, an axle freely revo luble in the bearings and'afriction-pulley secured to the axle, the combination there'- with of a forked locking bolt slid-ably supported and guided in theyokemember, the arms of said bolt arranged to register and interlock with saidapertured' portion of the respective bearings.

3. The combination in a textile spinningmachine, with a forked frameo-r yoke pro.- vided with a pair of horizontally alining recesses, of a tension pulley, bearing members-'removably seated ii -said recesses of the yoke, said'bearing membersihaving said tension-pulley revolub-ly j ournaled therein, each bearing member having" a groove or opening arranged at substantially right angles with its axial bore, and a bifurcated b olt 'having parallel arms slidably mounted in the yoke, the said 'arm-s o-f the bolt-being inregister With and normally engaging said grooves or openings andv arranged to lock both the said bearing members in position in the yoke simultaneously.

In testimony whereofll; have aflixed my g t r in vpresence of' twe witnesses.
